Cambodia in January offers a privileged window of mild temperatures and sunshine — a particularly appreciated time to discover this country of rich cultural heritage without enduring intense heat or seasonal rains.
This month falls within the dry season, during which the climate remains dry and temperatures moderate, offering especially favourable conditions for sightseeing, walks and relaxation. Travelling to Cambodia at this time means enjoying generous sunshine while avoiding the oppressive humidity typical of the warmer, wetter months. Whether in Phnom Penh, the vibrant capital, or Siem Reap, the gateway to the temples of Angkor, the climate is ideal for exploration.
The dry season also coincides with a period of lower tourist numbers, particularly outside French school holidays, which makes for a more authentic and peaceful travel experience. Stable weather conditions make trip planning easier, allowing visitors to better organise their movements and make the most of their stay. With temperatures generally ranging between 22°C and 32°C depending on the area, January stands out as an ideal month to explore Cambodia’s historical sites, picturesque villages and coastal beaches. Budget-wise, value for money is generally good outside of school holiday peaks.
Climate and Weather in Cambodia in January: What to Expect
Cambodia is governed by two major monsoons: the south-west monsoon, wet, from May to October, and the north-east monsoon, drier, from November to March. In January, it is this second monsoon that dominates, bringing almost constant dry weather and relatively cool air. This meteorological context significantly reduces the risk of rain, contributing to pleasant conditions for travel and outdoor activities.
Among the main tourist cities, Phnom Penh and Siem Reap each enjoy around 9 hours of sunshine per day, with fewer than one rainy day per month on average. Temperatures generally range from around 22°C at night to 31–32°C during the day, although occasional spikes can reach 34°C, or drop as low as 14°C in rare cases.
Phnom Penh in January: Atmosphere and Temperatures
The Cambodian capital enjoys very favourable weather in January. With less than one rainy day on average, visitors benefit from mostly clear skies — ideal for urban and cultural tourism. Daytime temperatures typically range between 22°C and 32°C, though the heat can feel intense at times, particularly in densely built-up areas. Wind is generally moderate, which helps reduce the sensation of discomfort.

Weather Conditions in Siem Reap, Gateway to the Angkor Temples
In Siem Reap, January weather is equally well-suited to tourism. With sunshine levels similar to Phnom Penh and barely more than one rainy day per month, the region is particularly pleasant for visiting archaeological sites. Temperatures are comparable, with average values between 22°C and 31°C, and extremes ranging from 14°C to 34°C in rare episodes.
To make the most of your visit, Siem Reap’s January weather encourages scheduling excursions in the early morning or late afternoon to avoid peak heat, while taking full advantage of the sunsets over Angkor Wat.
Budget and Tourist Season in January: What to Expect
In terms of budget, January falls within Cambodia’s low tourist season, which has a favourable impact on the cost of services. That said, flight prices and package holiday rates from France can fluctuate, particularly around French school holidays.
This pricing context, combined with favourable weather, makes January a highly recommended time to organise a private circuit in Cambodia, even on a tighter budget.
